Busy Hour and Traffic Intensity

The term busy hour is defined as the latest four consecutive 15-minute periods of the day during which the highest traffic carried value is recorded. If there is no traffic recorded, no busy hour information will be given. In this case, the busy hour field will indicate NONE. If the busy hour is to be calculated for a period longer than one day (24 hours), for instance, a whole week, this calculation must be done outside the exchange.
